TO ALL WHOM IT MAY CONCERN:

Be it known that I, J. WYATTBEID, of the city, county, and State of New York, have invented snewiaml useful Improvement in Steam Boilers; and I do hereby declare that the following is a full, clear, and exact description thereof. 7

My invention consists in constructing a steam boiler in such a manner that a greatly increased steamgenerating surface shall be obtained \vithout'materially increasing thesize or interfering with the most compact form of boiler. y i y I f And to enable others skilled in the art to make and use my invention, I will proceed to describb its con struction and operation, reference being bad to the accompanying drawings, which form a part of this specifi cation, and to the letters of. reference marked thereon.

Figure 1 represents a vertical section of my boiler (including the jacket) through the line y g of fig. 2.

Figure 2 is a horizontal section through'thc line a: :v of fig.

Figure 3' is a view of the top of the boiler without the jacket and with the bonnet oil'- Similar letters of reference indicate like parts. I

It willbe seen-that my boiler-isof the upright kind, with vertical tubes surrounded by a jacket.

A represents the jacket of the bbiler'; B is the shell which surrounds the tubes, and which forms the out side of the boilerproper; C and 0 indicate tubes through which the products of combustion pass, D is the furna :e; and E is a cap, covering the top of. the boiler proper, and made removable so that access may readily be had to the top'sof the tines C C'ivhen repairs are necessary. The products 'of combustion pass upward through those tubes or flues which stand directly over the furnace, and into the chamber formed by the bonnet orcover E. From this chamber thosmoke and other products of combustion take the course indicated by the arrest sand enter the flues or tubes G descending through these tubes to the'bottomof the boiler, they enter a chamber formed by the foundation, and which surround the ash box from this they ascend through the flue formed by the jacket A, and from thence into the chimney. d is the tube-sheet; f is the bottom of the waterleg through which the tubes C pass; g represents the water-space; h is the crown or tube-sheet over the furnace; j is the'cup-pit under the grate; k isthe furnace door; it is hinged to the shell, as seen in fig. 2. To make room for the door and the admission of fuel, one of the tubes U is left out, and a recess is also made in the jacket by deep flanges 1', which come in contact with the shell and surrounding the furnace door. a

It will be seen that in this boiler the tubes are all surrounded by water, and that the products of combiistion are retained in contact with water-plate surfaces until they have parted with their heat to a good degree.

Unlike the boiler in common use, the outside of my boiler is steam-generating surface, instead of being a sur face for the radiation and consequently the loss of heat.

Having'thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- The arrangement of the flues C C, removable cap E, shell B, jacket A, and furnace D, substantially as and for the purpose specified.
